This is intended for English text only. No definition oftitle case is universally accepted: all agree
that principal words are capitalized and common words like
for are not, but not which words fall into each category.
Generally words in all capitals are left alone: this implementation
knows about conventional mixed-case words such as LaTeX and
OpenBUGS and a few technical terms which are not usually
capitalized such as jar and xls. However, unknown
technical terms will be capitalized unless they are single words
enclosed in single quotes: names of packages and libraries should be
quoted in titles.
